I have been sick for a couple of years now. First symptoms were heat/sun rashes and severe dizziness. My initial visit with family doc. suspected something with my heart (especially after the sit down/sit up/stand up test) Heart beat skyrocketed upon standing. Anyway, went to cardiologist and did an echo. Found an enlarged left atrial valve and tricuspid and mitral valve regurgitation as well as AF. The Dr. said he did not think that was causing my symptoms...that's it. Began getting worse, constant nausea, vertigo and dizziness extremely severe at this point along with many other weird symptoms, but few blood test abnormalities: elevated bilirubin, severe Vitamin D and CoQ10 deficiency, and other things pointing to dehydration, which isn't possible. (I am 105 lbs and drink well over 80 oz water per day). I then got referred to neuro. whom did an MRI. Found a lesion on my brain, so then MS was suspected. Had an LP (ouch) with a blood patch to follow (double ouch), nothing there. Did the complete MS workup with another MRI over the next 9 months. Found 2 more lesions by this point, so Dr's convinced it is MS, but cannot diagnose without meeting certain criteria. I'm not sure that it is even MS, and the more I look into it, I'm thinking my heart could be the culprit? I've been in and out of ER's and Drs for the past 2.5 years with no results. Very frustrated, as well as emotionally, physically (and financially) drained. Anyone with similar heart findings and symptoms?
